If you're steady shooting that thing and know where to shoot it there is a good chance of hitting the spine on the Texas heart shot.

Know your gun and your target but above all know your abilities.....I'm not that good with a hand gun and wouldn't take that shot.

I dropped a deer in it's tracks with a .257 Roberts once that way..... Resting the rifle over a fence post and taking a careful shot works but the handgun is a totally different story. Be your own judge.
